Some drilling operators elect to re-use a portion of the wastewater to replace and/or supplement fresh water in formulating ,fracturing fluid, for a future well or re-,fracturing, the same well. Re-use of shale oil and gas wastewater is, in part, dependent on the levels of ,pollutants, in the wastewater and the proximity of other ,fracturing, sites that might re-use the wastewater.

Except for reported cation exchange and carbonate dissolution, this study showed several new findings, including nitrate adsorption/desorption and limited oxidation of pyrite in field ,flowback, samples that were dominated by mixing ,of fracturing, fluids and formation water, although oxidation of pyrite was observed in most of the laboratory experiments and expected to be comprehensive during field ,flowback, after hydraulic ,fracturing,.

Increasing the flow rate of the flowback fluid mobilized an additional 36% of colloids, due to the expansion of water filled pore space. This study suggests that hydrofracking fluid may also indirectly contaminate groundwater by remobilizing existing colloidal pollutants.",
